Question

Sen12+sen2=?
Ayudaaaa

Answer 1

TRANSFORMACIONES DE SUMA A PRODUCTO :

SEN(A)+SEN(B) = $2sen(\frac{A+B}{2})cos(\frac{A-B}{2})$

------------------------------------------------------------------------------------------

Sen(12)+sen(2) = $2sen(\frac{12+2}{2})cos(\frac{12-2}{2})$

Sen(12)+Sen(2) = $2sen(\frac{14}{2})cos(\frac{10}{2})$

Sen(12)+Sen(2) = $2sen(7)cos(5)$ >>>>Respuesta

espero se entienda xD

SALUDOS!!
